As Aristotle said everything in moderation including cigars and pizza.

Going into a full blown mega health nut phase is not very helpful either because the end result is not going to be pretty anyways.

Now if/when we start making serious life extension progress beyond 120 years with high quality of life then we can start talking.

If you look at the places where people live longest they are not health nuts especially and have quite a nice lifestyle. eg

>Ikaria, Greece, three times more likely to reach 90 than Americans, almost no dementia

>residents stay active through walking, farming and fishing, but they also make sure to take time out to nap and socialize. In addition to their Mediterranean diet, they eat a lot of wild greens and drink an herbal tea that’s full of nutrients. Their community lifestyle also encourages good health habits and regular social engagement.
